Backlash Adjustment
c. If backlash is not within specifications, correct by increasing thickness of one shim and decreasing thickness on the other shim by the same
amount.
d. Install shims and bearing caps. Torque bearing cap bolts to 70-85 ft lb, then rotate differential case assembly several turns in both directions.
e. Inspect backlash. If backlash is within specifications, proceed to step f. If not within specifications, repeat step c.
f.
Increase both lefthand and righthand side shims by 0.006 inch to provide proper differential bearing preload. Ensure shims are fully seated and
the case assembly turns freely.
g. Using suitable white marking compound applied to ring gear, inspect tooth mesh contacting pattern.
NOTE: Tooth mesh contacting pattern can be improved by installing the propeller shaft and axle assemblies and rotating both tires in the drive
and coast direction.
h. Contacting pattern should be within the primary area of the ring gear tooth surface avoiding narrow contact with the outer perimeter of tooth.
Inspect pattern on the drive (pull) side of the ring gear. If serious error is determined, inspect pinion shim selection.
5. Install axle housing cover, driveshaft and axle assemblies.
6. Fill rear axle assembly with axle lubricant. Remember to add friction modifier to Traction-Lok axles.
